Hi there Tommy, yes the 'mayonaise' is water which has emulsified with the oil . Basically, a gasket or seal has failed somewhere internally, which has let the fluids mix. You will probably also have some oil in your expansion bottle.

It will adversely affect the car's running, as compression is normally weakened.

I wouldn't drive it any more than is absolutely essential,(if at all) as you might cause the engine to fail altogether and it won't be repairable...

Hope I've managed to confirm what you already suspected.


This job should never be complete - the day I think I've done it all, is the day I resign.
